CHRISTIAN H. GOEBEL, OF PHILADELPHIA, PA., ASSIGNOR TO THE AMERICAN SEO'IIONAL ELECTRIC UNDERGROUND COMPANY, OF NEW JERSEY.

CONDUIT FOR E LECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 290,413, dated December 18, 1883.

Applicationfiled July 276, 1882. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTIAN H. GoEBEL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Underground Conduits for Electric Wires, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a top or plan view of the conduit embodying my invention. Fig. 2 is a transverse vertical section thereof.

Similar letters of reference indicate corre sponding parts in both figures.

My invention consists of a conduit constituting a curb, gutter, and portion of a street, each member of which is removable without disturbing the other members, and may be opened at top, in order that its interior may be conveniently accessible for laying, repairing, inspecting, testing, and removing the wires.

Referring to the drawings, A represents a conduit formed of tubes a b c, the tube moccupying the position of a curb of a street or roadway, the tube 1) that of a gutter, and the tube 0 that of the portion of the street adjacent to the gutter, each tube being disconnected from the other, so that the conduit may be readily laid, and either tube removed and reapplied without disturbing the remaining tubes, each tube, moreover, having a lid or cover, (1, so that access is readily had to the interior thereof for the purpose of laying, repairing, inspecting, testing, and removing the wires. On the sides of the tubes are hooks e, which are cast with or secured to the tubes,

tube 0 may also be wedge-shaped, so as to comi press the earth of the street.

provided on the inner faces of its sides with supports 0, which keep the individual wires separate.

In practice I prefer to use one tube for electric-light wires, one for telephone-wires, and one for telegraph-wires.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The wedge-shaped tube a, in combination with tube b, which it bears against, whereby said tube a is caused to compress the earth at its side and tighten the tubes together.

2. The wedge-shaped tube a, in combination with tube b, which it bears against, and

tube 0 on the other side of tube 1), the three tubes forming a curb, gutter, and part of a .street, and the pressure of tube a against tube 1) serving to compress the earth and tighten the tubes together, substantially as set forth. 7o
